Coloradoâs Scenic Million Dollar Highway: Silverton to Ouray. The scenic drive on Coloradoâs Million Dollar Highway (U.S. Route 550), from Silverton to Ouray, just might be the most eye-popping, awe-inspiring drive we have ever taken.
So, use caution and enjoy the magnificent scenery. The origin of the name Million Dollar Highway is disputed. There are several legends, though, including that it cost a million dollars a mile to build it, and that its fill dirt contains a million dollars in gold ore. First time you drive it, it's a real breath taker. Lots of sweaty palms.
